FEED-GUIDE FOR PRINTING- MACHINES.

SPECIFICATION forming part of Letters Patent No. 762,343, dated June 14, 1904.

Application filed May 1, 1903. Serial'No. 155,208. (No model.)

7 To all whom, it may concern.-

Be it known that I, ALBERT WILsoN Orro, printer, of the village of Osgood Station, in the county of Russell, Province, of Ontario, Canada, have invented certain new and useful .Improvements in Feed-Guides for Printingl\/Iachines,-of which the following is a specification.

My invention relates to improvements in feed-guides for printing-machines; and the objects of my invention are todevise a simple, cheap, and effective means for holding the edge of a piece of paper on the platen of the printing-machine, so that when the printing is done it will come in the right 'position upon the paper, further objects being to construct the device in such manner that it may be used as an extension feed guide-that is, one extending beyond the edge of the platen, so as to both support and guide the paperand to make the device in such away that it will not injure the platen-sheet or tear it when beingused; andit consists, essentially, of a holder comprising a'horizontal portion and a downwardly-extending flange adapted to be a strip slidably held on said horizontal portion and having guiding means at one end,

.the various parts of the device being con- 3.

structecl and arranged in detail, as hereinafter more particularly described.

Figure 1 is a perspective view of a platen of a printing-machine, showing my feed-guides in use. Fig. 2 is a section through one of the feed-guides and the platen. Fig. 3 is a perspective view of the platen of a printing-machine with two of the devices with attach.

ments enabling them to be used as extension feed-guides. Fig. 4 is a section through one 0f the feed-guides and the platen, as shown in Fig. 3. Fig. 5 is a perspective View of the feed-guide, the strip being reversed in its holder, and the whole being reversed in such a manner that it'fmay beusedas an extension feed-guide.

In the drawings like lettersof reference indicate corresponding parts in each figure.

A is the platen of a printing-machine.

B is the bail which surrounds the platen, and C is the platen-sheet, which is a sheet of any suitable way, but is preferably stamped out of the end portion of the strip D and bent around, as shown. The strip D is provided with a suitable securing device by which it may be held in position on the platen. The device which I prefer to employ for this purpose consists of the plate E, having a downwardly-extending flange a formed at one end thereof and adapted to extend between the platen and the bail. At the forward or opposite end of;this plate guides e e are formed, preferably by bending up a portion of each side of the plate. The rear end of the strip D is held in these guides with suflicient friction to prevent its moving therein longitudinally unless actually moved by hand.

It will now be seen that when one or more of the devices as above described is or are secured to the platen, the flanges Z being in alinement, a piece of paper upon which printing is to be done may be placed with its edge along the alinement of the flanges d in such a manner that it will be brought into the correct position and all other similar pieces could be printed in an exactly similar way, or, in other words, with a margin of equal width.

It is frequently desirable to leave a margin on the paper to ,be printed of such a width that the paper becomes wider than the platen. It is obviously necessary in such a case to provide guides which will extend beyond the edge of the platen and support the paper and at the same time hold, its edge at the proper distance and in the proper alinement. My device may be used in this way (see Fig. 5) by simply pulling out the. strip D from the guides a and inserting it in them; from the opposite end, at the same time reversing the plate E, so that it will extend beyond the edge of the platen. Itis preferable, however, when using the device as an extension feed-guide to provide additional attachmentsnamely, a supporting-piece F and an adjustable guide G. (See Figs. 3 and 4t.) The supporting-piece F consists of a body having upwardly-turned sides forming the guides f and a downwardlyextending flange f, adapted to fit in between the bail and the platen, thereby forming a support. The slidable guide G, which is adapted to be attached to the strip D, consists of a flat portion g, having the lower edges. bent downwardly and inwardly to form guides for the edges of the strip D. A forward upright portion or flange g is formed thereon with an overhanginglip which is adapted to hold down the edge of the paper to be printed on in the same manner asthe projection d acts when the guide is being used, as shown in Figs. 1, 2, and 5.

It will now be seen that I have devised an extremely cheap, simple, light, and easily-operated feed-guide for printing-machines. In feed-guides used in the past there were a number of disadvantages which were diflicult to overcome. For instance, the method of securing the guides generally necessitated the use of spikes or pins, which had to be forced into the paper of the platen, the result being that the platen sheet had to be renewed very frequently, as it became torn after a very short period of use. They were complicated and expensive, and separate feed-guides had to be employed when it was necessary to have an extension feed-guide, and a further disadvantage was that' the extension feed-guides were generally made so heavy that it was necessary to bend the securing-piece completely round the bail, so that they could not be removed without unbending such securing-piece, and the bending and unbending very soon would cause a break, with consequent inconvenience and expense. It will be seen, however, that my device obviates all these difliculties. It is simple and cheap in construction, may be adjusted to any desired position, and may be used both as an extension and as an ordinary feed-guide. It is sufficiently light to be supported by a supporting-piece, which is simply inserted between the bail and the platen without bending, and

invention on the market slight alterations may be made in the construction and arrangement of the various parts without departing from the spirit of my invention. For example, the form of the securing-piece E might be altered in detail, also the form of the strip D and of the guiding-piece Gr; but it is to be understood that I do not wish to be limited to the form as shown and described.

What I claim as my invention is- 1. In adevice of the class described, the combination with the holder comprising a horizontal portion having guides at the sides thereof and a vertical portion or flange adapted to extend between the platen and the bail, of a strip slidably held in the guides, said strip being provided at one end with adownwardlyextending face or flange of greater width than the strip, the lateral extremities of said flange being bent rearwardly and a tongue centrally located at the forward end of the strip and extending forwardly beyond the vertical face or flange as and for the purpose specified.

2. In a device of the class described, the combination with a holder comprising a horizontal portion provided with guides and a vertical portion adapted to extend between the platen and the bail, of a strip slidably secured in said guides and adapted to extend outwardly beyond the platen, a guide slidably secured to the said strip and comprising a horizontal portion having guides formed at the sides thereof to engage the edges of the strip, a vertical guiding face or flange at the forward end of said horizontal portion and of greater width than the horizontal portion, the lateral extremities of said vertical flange curving rearwardly and an overhanging centrally-located tongue or upper guide extending forwardly and upwardly from the upper edge of the vertical flange or face as and for the purpose specified.
